I updated R to 4.1.0 and am trying to install rstan from the source (install.packages(c(“StanHeaders”,“rstan”),type=“source”)
The StanHeaders install correctly, however when it starts to install rstan I get this:
Warning message: package ‘rstan,’ is not available for this version of R
I am currently running R on a mac with High Sierra 10.13.6.
Any help moving forward would be great!
